T21

A planned successor to the M3 and M5 Light Tanks, this tank was based around the T20's mechanical parts. Based around a 76mm gun and weighed 24 tons. However, the design was held back back due to its rather heavy weight. Eventually, it was superseded by the T24 program, which was standardized as the well known M24 Chaffee.

The T21 is a lighter variant of the T20 medium tank. As such, it is rather large for a light tank, but it has good maneuverability and a great view range, on top of having a good power to weight ratio. Unfortunately, it's hampered by its low top speed. Additionally, it uses the same gun as the M4 E8/E2, having rather low penetration in exchange for a high rate of fire and DPM.
